Why Do Teeth Turn Yellow?
For many people, understanding why teeth turn yellow begins with everyday habits but natural biology plays a big role too. Most discoloration develops slowly, which is why it becomes more noticeable over time. If you’ve ever caught yourself wondering, “Why Are My Teeth Yellow?”, the answer might not be as simple as you think. Let’s look at what really happens behind the scenes:
- Enamel Wear: The enamel on the outside of the tooth works like a protective shield. As it wears down with age or grinding, the yellow dentin inside starts to show through. Even people with excellent dental hygiene experience this, making it one of the most natural reasons for discoloration.
- Dietary Choices: Coffee, tea, wine, curries, and dark-colored drinks are among the most common foods that stain teeth. Their pigments settle into enamel pores over the years and gradually turn teeth yellow.
- Lifestyle Factors: Smoking, vaping, and poor dental care dramatically accelerate staining. These habits combine surface stains with deeper enamel damage, making yellowing more intense and long-lasting.
- Internal Factors: Genetics and certain medications can affect tooth color from within. In these cases, discoloration isn’t caused by lifestyle choices, it’s biological, which makes prevention more challenging without professional treatment.
- Hidden Culprits: Even healthy foods like berries, beetroot, or tomato-based sauces contain strong pigments that add up over time. They may not seem harmful, but they can silently contribute to noticeable staining.
When people understand What Causes Teeth to Be Yellow?, they gain control over habits and routines that protect their smile long term.
